This report provides a comprehensive techno-economic assessment of various hydrogen production and purification technologies. It begins with an introduction highlighting the increasing importance of hydrogen in the context of clean energy and the reduction of carbon emissions. The report then delves into the current state of hydrogen production, emphasizing the dominance of steam methane reforming (SMR) and its environmental drawbacks, such as CO2 emissions. It explores alternative methods like electrolysis powered by renewable sources (solar and wind), detailing the process, its advantages (zero greenhouse gas emissions), and the potential for cost reduction with technological advancements. The report also examines SMR with carbon capture and storage (CCS) as a means to produce low-carbon hydrogen. It includes a system overview, discussing components like PV cells, electrolyzers, and storage systems. The report presents current and future cost estimates for hydrogen production via PV and electrolysis, along with an analysis of the different electrolysis technologies (alkaline, PEM, and SOE). The report is based on several research papers, the assignment analyzes the economic viability, efficiency, and environmental impact of different hydrogen production pathways, offering insights into the potential of these technologies in a sustainable energy future. The report provides detailed information on each method's processes, costs, and environmental impacts, making it a valuable resource for students studying environmental engineering and related fields.
